LUDWIG POSCH, OF JERSEY CITY, NEW JERSEY, ASSIGNOR- OF ONE-HALF 'TOMAXIMILIAN LANCER, OF NEW YORK, N. Y.

VISE.

To all wlzom it may concern:

Be it known that I, LUDWIG Poser-I, a citizen of the United States, anda resident of Jersey City, in the county of Hudson and State of NewJersey, have invented a newand Improved Vise, of which the following isa full, clear, and exact description.

This invention relates to gripping devices and particularly to animproved conof all kinds to grip articles of any shape and firmly holdthe articles in position.

The object in view is to provide a gripand other mechanism which willgrip articles of different sizes and shapes and will at the same timeaccommodate itself to the particular shape of the article being gripped.

Another object of the invention is to" provide a gripping jaw formedwith a number of nested parts which will automatically assume a straightline or an irregular line as pressure is brought to bear thereon so asto accommodate different shaped articles.

A still further object, more specifically, is to provide a vise with apair'of rounded sockets in the opposing jaws and gripping means fittedinto said sockets arranged in groups with automatically adjusting grip-'ping parts.

In the accompanying drawings- I .Figure 1 is a top plan view of thedevice disclosing a gripping aw structure embody-' ing the invention.

Figure 2 is a side view of the structure shown in Figure 1.

Figure 3 is a top plan view of the jaw shown in Figure 1, the same beingshown re-' moved and in gripping action for gripping a diamond-shapedarticle.

Figure 4; is a sectional view through Figure 1 approximately on lineIr-4:.

Figure 5 is a detail perspectiveview of one of the gripping parts shownin Figure 3. Figure 6 is a front view of an arc-shaped member adapted'tocarry two of the gripping parts shown in Figure-5, said member embodyingcertain features of'the invent-ion.

Referring to the accompanying drawings by numeral, 1 indicatesthe baseof a vise which in general design may be of any kind and which isprovided with jaws 2 and 3. These jaws may be arranged so that one willbe stationary and the other movable or both movable. The detailconstruction of thebase 1 and the jaws 2 form no part of the presentSpecification of Letters Patent.

turn are provided with a pair of sockets 14:

and 15 for receiving crescent-shaped members 16 and .17.. Each of themembers 16 and 17 is provided with two arc-shaped notches 18 and 19 for,receiving the substantiallycrescent-shaped clamping members 20 and Y21.The contactor gripping face of members 20 and 21 may be as shown in thedrawing or ma have some other configuration without departing from thespirit of the invention. However, these members are posi-.

'tioned to rotate on a central axis while fitting in the notches 18 and19. The. same is true of members 15 and 16 as well as members 12 and 13of the crescent shaped member 7. All of these members are adapted toautomatically move or adjust themselves to present a straight,.curved orirregular clamping surface to an article according to the shape of thearticle as shown in Figure3. For instance, when the parts are in theposition shown in Figure 1 and it is desired to insert a diamond-shapedarticle, as shown in Figure 3, the jaws are opened wide enough toreceive the article and-then the article placed inposition and helduntil the jaws are closed. During the closing action the variouscrescent-shaped members will automatically move to the position shown inFigure 3 and will consequently, grip evenly the article. In this way,the article may be firmly gripped in place with the desired pressurewithout crushing any part thereof.

In forming the various crescent-shaped members they are preferablyprovided with overhanging shoulders 22 and 23 at each end as shown inFigures 4 and 5. These overhanging shoulders are adapted -to fit over atongue structure 24 on the next adjacent crescent-shaped member.

This con-' struction holds the various members together in their propercentral position while allowing a free rotary movement thereof forpermitting automatic adjustment and, consemay be readily clamped With aneven pressure over the clamped surface.

' The invention has been illustrated as being applied to an ordinaryvise but it is evident that it may be used on a. pipe vise or any otherform of vise and if desired chucks for lat-hes as Well as othermachinery of said javvs, each gripping structure consisting of apluralit of elongated nested members, said mem ers each being arc-.

shaped in cross section and having at their upper and lower ends shapedshoulders overhangin the convex face of the member and having theiropp'osmg faces undercut, all of the members except the outermost oneshaving arc-shaped grooves in their ends forming intermediate dove-tailtongues having concave faces, fitcorrespondingly v and in all theseuses, automatically adjusts ting upon the adjacent members between theitself to take care of any irregularity in the article clamped.

Vhat I claim is A vise of the character described, comprising a body, apair of jaws mounted on the body, and a gripping structure for eachshoulders thereof and engaged by the said shoulders, whereby the saidmembers are free to rotate on their own axes, but are securely heldagainst accidentaldispla'cement.
